About the test of domestic 26650 lithium battery

At present, the domestic manufacturer of 26650 lithium battery is not as much as 18650, apart from the X fire doesn't count, I know less than ten (there must be something I don't know), King Kong has done earlier power batteries, Li Lang and Meng Ke for a dynamic model, and domestic force, the force of the lithium-ion batteries (internal resistance is big, the steel rust, positive negative rust).

This blue is said to be in a Shenzhen lithium battery company engineer of starting their own business, after the measured 2.5 A, 5 A, 10 A, 20, A discharge capacity is no problem, late 20th a discharge at higher temperature (room temperature is 20 degrees without cooling, before LG series 20 A discharge with fans auxiliary cooling), for individual players, there's not a good cooling case, I suggest that discharge within 15 A (constant current), 20 A short time no problem. Leather printing word 50A should be a good heat dissipation of the case. Finally, I made it clear that 50A on the cover means 5000mah, but it is actually the battery of 5C discharge, which is not much different from the 20A measured by the shopkeeper. However, 5C discharge still needs to solve the problem of heat dissipation.

This battery is very good, ternary is 2.75v, this battery is 2.5v, and 50A is 5000mah, the current market price is 28 a.

There are three main differences between the 26650 lithium battery and the 18650 lithium battery:

1, the battery volume is different; 26650 volume is larger than 18650, their cell height is the same.

2, the cell diameter is different, 26650 cell's diameter is 26mm, and 18650 cell's diameter is 18mm.

3, the battery capacity is different; the battery capacity of 26650 under the same battery material is larger than the battery capacity of 18650, assuming that the same ternary material 26650 battery is generally around 5200mAh.

The capacity of the 18650 battery is about 2600mAh.

4, the application environment is different; 18650 lithium batteries are used in lighting fixture battery, industrial supporting lithium battery pack, power tool battery and electric bicycle battery.

Power lithium battery packs and other aspects, and 26650 lithium batteries are used in integrated solar street light lithium battery packs, energy storage stations, solar energy storage batteries and so on.
